HASP SEAL-LOCK.

Specification of Letters Patent.

Patented Aug; 1, 1916.

Application filed October 2 7, 1911'. Serial No. 657,014.

To all whom it may concern:

Be it known that I, MELVIN H. VAN H. BATTENBERG, 'acitizen of the United States, residing at Chicago, in the countylof Cook and State of Illinois,have invented a certain new and useful Improvement in Hasp Seal-Locks, of which the following is a specification.

This invention relates to hasp seal locks, and has forits object to provide a new and improved device of this description.

The invention'is illustrated in the accompanying drawings, wherein Figure 1 is a plan view of a lock embodying the invention with the hasp hanging in its inoperative position. Fig. 2 is a view showing the. parts of the lock in their operative position with the seal in place. Fig. 3 is a sectional View taken on line 3-3 of Fig. 1. Fig. 4 is a view of the lock case as seen from the back with the closing plate removed. Fig. 5 is a sectional view taken on line 5-5 of Fig. 2.

Like numerals refer to like parts throughout the several figures.

The lock herein illustrated is provided with a hasp and associated parts and a seal which must be broken, crushed, destroyed, defaced or removed'before the lock can be opened, the seal being so acted upon that it can not be replaced without indicating that the lock has been tampered with.

This invention has a wide range of adaptability and is particularly designed for use in connection with railway car service, where the conditions require alooking deviceof extreme simplicity and one which will not be'rendered inoperative by dust, dirt and weather conditions. It is also necessary, that the mechanism on the lock shall be so protected-that it cannot be tampered with by unauthorized persons without leaving noticeable evidence thereof. By means of the present invention these results are secured.

Referring now to the accompanying drawings, I have illustrated a, lock for use on railway cars. This lockis provided with a hasp 1, movably fastened in position by the fastening piece 2. This hasp is made up of a single piece of material and 1s provided with a seal receiving recess 3, into which the seal 8 is received. Associated the other direction.

with-the seal receiving recess are the seal engaging parts 4:, which hold the'seal in position, and which also enga'geit in such a manner as toassist in its mutilation. The metal back of the seal receiving space is cut away as shown at 5 so as to permit the passage of the seal mutilatingpart-6. At the bottom of the seal receiving space there are preferably provided openings'5? which permit the pieces of seal when broken to fall out of the seal receiving space and which also prevent packing of cinders and dust in the corners of the seal receiving recess. The seal mutilating partr6 is associated with a casing separate from the hasp and is arranged so that it can be rotated in one direction but is locked against rotation in the opposite direction. When the parts are in their operative position, the rotation of the seal mutilating part, after it reaches itsoperative position, is prevented by the hasp. This seal mutilating part may be constructed and arranged and dis posed in any desired manner. As herein shown, it is connectedwith a rotatable part 7 mounted in the casing-8 and provided with means for preventing rotation in one direction but permitting free rotation in In the construction shown this means consists of a ratchet 9 having two ratchet teeth, said ratchet being engaged by a pawl 11, the pawl passedinto engagement therewith by a suitable spring 12 (see Fig. l). It will be seen-that the ratchet is free to be rotated in thedirection of the arrow and that the rotation in the opposite direction is prevented by the pawl 11. The casing 8 is provided with a movable bottom 13, which is inaccessible when the plate is fastened in position, and hence the mechanism is entirely sealed and pro or other part 15, which holds it in its operative position. If desired, a pin 16 may be passed through this staple.

I have described in detail a particular construction embodying my invention, and it is evident that the parts may be varied in form, construction and arrangement without departing from the spirit of my invention, and I therefore do not limit myself to the particular construction shown.

The use and operation of my invention are as follows: When the lock is unlocked,

the parts take the position shown in Fig. 1.

When it is desired to lock the lock, the seal 3 is inserted in the seal receiving space and the hasp moved over the staple 15 as shown in Fig. 2. The seal mutilating part is nowin position shown in Fig. 1. This seal mutilating part is then rotated so that a portion thereof passes in front of the seal as shown in Fig. 2. The seal mutilating device, when in this position, cannot be rotated backward because of the ratchet and pawl and cannot be rotated any farther in a forward direction because of the hasp. This'seal mutilating part also engages the seal so as to prevent the hasp from being moved off of the staple 15 without breaking or mutilating the seal. It will therefore be seen that the door or other device is now locked in such a manner that it can not be unlocked without breaking or mutilating the seal, so that there will be plain evidence that the lock has been tampered with. When it is desired to unlock the lock the pin 16 is removed and the hasp moved outwardly. The seal mutilating part 6, during this movement, engages the seal 3*, preferably a frangible seal, and breaks it so that a new seal is necessary before the door can be again locked. When the lock is unlocked the hasp is moved to the position shown in Fig. 1 and the seal mutilating part to the position also shown in Fig. 1. The lock is then readyto be again used when a new seal is placed in the seal receiving recess. It will thus be seen that by this construction a simple lock is provided. with its working parts so protected that they can not be rendered inoperative by accumulations of dirt or cinders or interfered with by persons desiring to prevent the proper locking of the device. It will also be seen that any one tampering with the lock will leave plainly visible evidence of that fact. It will further be noted that because of the simplicity of the device and the protection of the parts they may be thickly painted to protect them from rust when the door itself is painted, and it will further be noted that the lock itself may be dipped in paint or other preservative after being assembled -without interfering with its operation.

I claim: 1. A look comprising a laterally movable hasp adapted to be movably connected at one end to a fixed part, said hasp provided between its ends with a seal receiving recess adapted to receive a frangible seal and open at one of its borders so that the seal may be received therein when the hasp is in its unlocked position, said hasp adapted to be moved laterally into and out of its locking position, the seal moving laterally with the hasp, and a seal mutilating part separate from the hasp and adapted to be moved so as to project over the seal when the hasp is in its locking position, whereby when the hasp is moved from its locking position to its unlocking position the seal mutilating part engages the seal and mutilates it.

2. A look comprising a hasp made of a single piece of material and having a seal receiving recess, a seal mutilating part located at one side of said hasp separate from said hasp, and adapted when the parts are in their operative position to mutilate the seal when the hasp is moved; the portion of the hasp back of said seal being cut away so that said mutilating part may pass therethrough after the seal has been mutilated.

3. A lock comprising a hasp provided with a seal receiving space for receiving a frangible seal, a seal mutilating part separate from the hasp and associated therewith, said seal -mutilating part adapted to be rotated in one direction, and means for preventing the rotation thereof in the other direction; and means separate from said seal for preventing the rotation of said seal mutilating part in said one direction while in its mutilating position.

4. A look comprising a hasp, recessed to receive a frangible seal, a seal mutilating part associated with said hasp and free to rotate in one direction but locked against rotation in the other direction, said hasp obstructing the free rotation of the seal mutilating part when the parts are in their operative position.

5. A look comprising a casing adapted to be fastened in position, a device within said casing adapted to be rotated in one direction and locked against rotation in the other direction, a seal mutilating part outside of the casing connected with said device and a hasp recessed to receive a frangible seal associated with said mutilating part; and means separate from said seal mutilating part for holding said hasp in operative relation to said seal mutilating part.

6. A look comprising a hasp having a seal receiving recess, a seal mutilating part associated with said hasp and free to rotate in one direction but locked against rotation in the other direction, and a stop on said hasp separate from said seal adapted when the hasp is in position to prevent free rotation of said seal mutilating part.

7 A lock comprising a hasp having a seal receiving recess for receiving a frangible 10 position being cut away so that the pressure of the seal mutilating part on the seal forces a portion thereof through the cutaway portion of the hasp.
